I have a big soft spot for classically-trained aging Shakespearean sellouts: Ian McKellen, Patrick Stewart, John Gielgud, Timothy Dalton (thanks to Russell T for casting him as Rassilon!). Which brings me to science fiction: Doctor Who, Star Trek, Futurama. More cartoons: Family Guy is wicked. Hugh Laurie is genius, as was Arrested Development. I can be a sucker for gorgeous cinematography (Zhang Yimou comes to mind, as do Wings of Desire and Tom Ford's recent film) and high camp (Suddenly Last Summer).
I grew up with some classical piano training, and more recently I've fallen in love with a wide range of classical music. It doesn't get much better than the Brahms symphonies. I have a thing for Scandanvians -- Sibelius, Salonen, and a very pretty Sigur Rós song as performed by the Kronos Quartet (Flugufrelsarinn). I also enjoy listening to jazz (Coltrane is a good example). I like songwriters including Loreena Mckennitt and Vienna Teng. I even have a recurring tendency to play highly stereotypical gay dance music, but please don't tell anyone.
I enjoy foods with some complexity to them; I like French restaurants and certain types of Chinese, but also trying new things in just about any shape or form. I'm always up for an afternoon of wine tasting. I love the food in New Orleans and I can make a mean jambalaya.
